By the full quantum theory,the dynamical evolution of the motion of C.M of two atoms in the two-mode squeezed vacuum states was studied.Through caculating,the reduced density matrix of the relative position of two atoms and decoherence factor were obtained.It was found out:1)the spontaneous radiation of the couple of atoms could induce the decoherence for the motion of C.M in the two-mode squeezed vacuum state;2)the phenomenon of quantum decoherence became more clear with the squeezed factor changing bigger.
